Abstract：
:Human papillomavirus (HPV) infection is the primary cause of cervical cancer. The Quantivirus(®) HPV E6/E7 RNA 3.0 assay (DiaCarta, CA, USA) detects E6/E7 mRNA of 13 high risk subtypes and 6 low risk subtypes. Cervical specimens collected in PreservCyt were processed for HPV detection. Cervical biopsies were taken only from those women with abnormal colposcopy. 200 out of 272 (73.5%) cases were mRNA positive. The percentage of HPV E6/E7 mRNA positive samples increases with the severity of the cytological diagnosis, but not in histological diagnosis. In 146 patients with both tests, the E6/E7 mRNA assay had significant higher positivity rate than the Hybrid Capture 2 assay (75.3% versus 62.3%). The HPV mRNA assay and the HC2 assay had the same sensitivity of high grade cervical intraepithelial neoplasia (CIN 2+), 82.4% (14/17) (95% confidence interval [CI], 64.3, 100). However, the specificity of CIN 2+ for the HPV mRNA assay was significantly lower than HC2 assay. Receiver operating characteristic curve analysis was used to compare the diagnostic performance of the E6/E7 mRNA and HC2. E6/E7 mRNA achieved 58.8% sensitivity with 74.1% specificity, HC2, achieved 47.1% sensitivity with 70.7% specificity. The overall performance of HPV E6/E7 mRNA assay for detecting CIN 2+ was lower than HC2. This study does not support the use of this assay in screening for cervical cancer prevention alone.
